FIBE-EXTINGUISHER.

Specification of Letters Patent.

Application filed March 11, 1909. Serial No. 482,650.

To all whom it may concern:

Be it l-inown that I, Gnonon C. Maonm, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain Improvements in FireExtinguishers, otwhich thefollowing is a specification.

The objects of this invention are to enable a fire extinguisher and itsaccessories to be more conveniently and compactly packed for shipmentfrom the factory to the customer or user; to avoid the necessity of anumber of small packages or parts to accompany the tank portion or fireextinguisher-proper; to utilize the interior space of the fireextinguisher for containii'lg such accessories; to prevent the interiorparts of the lire extinguisherand said accessories from shaking orrattling around inside the tank during transportation; to save labor andexpense in packing and shipping the fire extinguishers, and to obtainother advantages and results as may be brought out in the followingdescription.

Referring to the accompanying drawings, in. which like numerals ofreference indicate corresponding parts in each of the several figures,.l igure l is a plan of a fire extinguisher embodying my improvements;Fig.

2 is a similar View with the screw cap or closure removed; Fig. 3 is aside view of the tire extinguisher partly in central section on line 3,2:) Fig. 2, and Fig. l is a de tail cross section taken on line 4., 4;of Fig. 3.

In said drawings, 10 indicates the usual cylindrical tank of a hand lireextinguisher provided with a discharge pipe 11 and a handle I12 .t'orhandling or supporting the extinguisher. Said tank 10 provides above itsbottom 13 a chamber adapted to contain a solution of bi-carbonate ofsoda or the like, and access to which chamber is had through a bushing14 inserted in the top of v the tank. This bushing is externallythreadcd at its projecting portion to receive a screw cap or closure 15,and also has lugs 16 projecting radially inward and forming lips orstops for the flange 17 of the top ring 18 of a bottle cage. This acidbottle cage, for purposes of illustration, 1 have shown of substantiallythe construction shown in Patent No. 735,480, it having downwardlyextending straps 19 crossing beneath the bottle 20, and its top ring 18being split to allow spreading to remove the said bottleQt).

in carrying out my invention. a pasteboa'rd lube Ell is inserted throughthe top opening of the lire extinguisher tank, so that said tube standsat its lower end upon the bottom 13 of the tank and at its upper endlies within the bushing 14, or lugs 16 thereof. The proper amount ofbi-carbonate of soda imcessary to charge the fire extinguisher iscontained in a paper bag 32 adapted to enter the said pasteboard tube21, and the mouth of said bag is tied with a cord 23 which at its otherend is attached to the bottom of the acid bottle cage 2st, as at The bagis then dropped into the pastcboard tube 2.1 so that it rests upon thebottom thereof or upon the bottom of the tank )3, andthe acid bottlecage enters the top of the pasteboard tube 21. and engages at its topring 18 the bushing l-land lugs 16 thereof, so that said acid bottlecage is supported as usual. There is sullicient length of the cord 23between the bag and cage 24. to enable said bag to rest upon the bottomof the tube or be supported by the bottom l3 of the fire extii'iguishertank.

The lead stopper 26 for the acid bottle 20 is put in the top of the bag22 upon the bicarbonate of soda therein, as shown. The acid bottle 20has been filled with the proper amount of acid, as usual and said acidis confined for shipment by the ordinary rubber stopper 27. The screwcap or closure 15 is then screwed firmly upon the top of the fireextinguisher tank, and the [ire extinguisher is ready for shipment fromthe factory.

It will be understood that the acid bottle cage 24- depending into thetube 21 holds said tube in central position of the fire ex tinguishcrtank, and said tube serves during shipment to retain the bag 21 againstundue mm'ement or shaking around. When the fire extinguisher is to becharged by the purchaser, the acid bottle cage is first taken out, andby the string 23 the bag 22 is also withdrawn, the tube 21. serving as aguide for said bag. The tube 21 may then be removed, the bag 22 detachedfrom the said bottle cage, the stopper 26 taken out of the bag, and therest of its contents poured into the fire extinguisher tank and mixed.with water as' usual. The rubber stopper 2"?- is then removed from theacid bottle, the lead stopper 26 inserted as usual, and the .cage placedin the topof the fire extinguisher, asisordinarilydone. A

It will be understood that by my 1mproved construction, the fireextinguisher as sent out from the factory contains within itself,securely acked, everything necessary for charging t e extinguisher.There are therefore no outside accompanying packages to carry thedifferent accessories, such as would not only add to the bulk of thepacked fire extinguisher but also render said accessories liable to lossor breakage. By my-invention the said accessories are absolutely safefrom damage or loss, are occupy-ing what would otherwise be waste space,

and can be packed without any special care or attention. I thus. savelabor and expense not only in preparing fire extinguishers for shipment,but also in the actual shipplng of the same for transportation of them.

'It will be understood that the tube '21 may be of any suitable materialor construction, and that its lower end may be either closed or open.Also the bag 22 may obviously be of any suitable material .orconstruction, or under some conditions dispensed with entirely andthebi-carbonate of soda or other dry chemical retained in the lower end ofthe tube 21 by other means.

Having thus described the invention, What I claim is.

the lower part of said tube against distribution, and a cap or closurefor said tank.

2. In a fire extinguisher, the combination of a tank having an openingat its top, a

tube in said tank supported by the bottom 7 of the tank an acid bottlecage supported on said tank at said opening its top and depending intothe said tube and fitting the same, means in the lower part ofsaid-tube.

for confining a dry chemical against distribution, and a cap or closurefor said tank.

3. In a fire extinguisher, the combination of a tank having an openingat. its top, an acid bottle c'a'ge supported on saidtank at said openingand projecting into the inte-.

rior chamber thereof, a tube fitting upon said cage and extending beyondthe .same 'into the interior chamber of the tank, means in the inner endportion of said tube beyond the, said cage for confining adry chemicalagainst distributiom-and-a cap or closure for said opening of the tank.

4. In a fireiextmgulsher, the combination I of a tank having an openingat its top, an acid bottle cage removably supported on said tank at saidopening and projecting into the interior chamber thereof, a tube fittingupon said cage and projecting therebeyond into the interior of the tank,a container adapted to confine a dry chemical arranged within said tubebeyond the inner end of the cage, means connecting said container tosaid cage, and a cap or closure for said container.. g

5. In a fire extinguisher, the combination with a tank having an openingat its top, a

tube in said opening extending into the interior of the tank, acontainer in said tube adapted to confine a dry chemical, means attachedto said container and accessible from the outside of the tank forsliding said container out, of said tube,-and a cap or closure for thetank.
